AUGUST 3. SCHOENKY, OF SOMERVILLE, MASSACHUSETTS, ASSIGNOR TO REECE SHOEMACHINERY COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MAINE.

INSOLE AND PROCESS OF MAKING THE SAME.

Massachusetts, have invented an Improvement in Insoles and Processes ofMaking the Same, of which the following description, in connection withthe accompanying drawing, is a specification, like characters on thedrawing representing like parts.

Thisinvention relates to a composite insole composed of two layers ofthin leather or other sheet material. 1

*It has heretofore been proposed to make acomposite insole composed ofan outer member or layer which'has its edge folded over on the body ofthe material and then bent upwardly therefrom, and an inner layer whichhas its edge folded upwardly and which is received within the upturnededge of the outer layer. Examples of insoles having this constructionare shown in United States Letters Patent to George Coleman, No.1,062,536, dated May 20, 1913, and to E. H. Taylor, No. 1,14t5,094,dated July 6, 1915. a I The insole of the present invention is of thegeneral type illustrated in the abovementioned patents and the objectsof the invention are to provide a novel insole of this type having aninseam-receivingrib so constructed that it can be readily beaten downin:a beating-down machine after the insole has been sewed to the upperand welt, and alsoto provide" a novel method by which this insole can bemade.

In making my improved insole, Ifirst make the inner member from a blankof sheet material of the proper size and shape by folding the edgeportion of the blank over onto the body thereof. This folded blank isthen placed on another blank of sheet material from which the outermember is formed, said two blanks being so positioned relative to eachother that the edge portion of the blank for the outer member willproject beyond the folded edge of the inner member. The projecting edgeof the outer membei' isthen'folded back on itself into contact'with theperiphery of the fold- Specification of Letters Patent.

ed blank, the peripheral edge of the outer member being shaped topresent a lip. In this folding operation of the outer member, the foldedinner member has the function of a die or former to assist in giving theproper shape to the outer member.

In orderto give a better understanding of my invention, I haveillustrated in the drawings a selected embodiment thereof which will nowbe described, after which the novel features will be pointed out in theappended claims.

Figure l'of the drawings is a view of the blank from which the innermember is formed; Fig. 2 shows said blank with the edge portion foldedover onto the body thereof; Fig. 3 is an enlarged section on the line33, Fig. 2; Fig. a shows the blank from which the outer member isformed, said view showing in dotted lines the folded inner memberpositioned on the outer member; Fig. 5 is a sectional perspective viewshowing the folded inner member positioned on the outer member beforethe edge of the outer member is folded; Fig. 6 is a similar view showingthe edge of the outer member folded; Fig. 7 is a perspective View of acompleted insole made in accordance with my invention.

The inner and outer members of my improved insole are indicated at 1 and2, respectively, and each of these is made of sheet material which maybe either relatively-thin leather or fabric, or any other similarmaterial. The inner member 1 has the edge portion thereof folded back onshown atG in Fig. 1. This blank has the general shape of an insole andis provided near the heel with the inwardly-directed slits 7. The edgeportion of the blank 6 from the slit forwardlyis then folded overagainst the body thereof, as shown in Figs. 2 and 3, the folded-overedge being indicated at 3. The blank from which the outer member 2 isformed is shown in full lines at 8 in Fig- 4:. After the inner member 1has been formed, as shown in Figs. 2 and 3, said inner member is placedon the blank 8 so that the heel portions of the inner member l and blank8 coincide with each other; This relative position of the inner memberand blank 8 is shown in dotted and full lines Fig. 4. The blank 8 is ofsuch a size and shape that when the inner member is thus positionedthereon, the edge portion 9 of the blank 8 will project beyond the innermember. After the inner member and blank are thus positioned, theprojecting member 1. 111 thus folding the projecting portion 9 of theblank 8, the folded inner member 1 of the insole acts as a die or formerto assist in giving the proper shape to the folded edge portion of saidblank.

It will be understood, of course, that if necessary the blanks may beproperly tempered before the folding operation, as is customary whereleather or similar sheet material is to be folded. I also wish to statethat the folding of the blanks will preferably be accomplished by meansof suitable dies which may be heated in the usual manner if necessary toassist in settingthe folds. W' hen this is done, both blanks will besubjected to pressure and heat. to produce and set the folded portionsthereof. The inner and outer members may be secured together in anysuitable way. I will, preferably, however, apply a coating of ad hesivematerial to the face of the folded inner member 1 that contacts with theblank 8 and will subject the inner and outer membersto pressure eitherduring the folding.

One advantage of my improved insole is that it provides aninseam-receiving rib which furnishes ample strength to hold the inseamstitches, but which can be readily flattened out, thus avoiding thepresence of an objectionable rib beneath the inner sole of a shoe whichoften produces. more or less discomfort to the wearer. It will be notedthat the strength of the inseain-receiving rib is the combined strengthof the portion 5 of the outer member and the infolded portion 3 of theinner member, and even when both of these members are made of thinleather or fabric, the combined strength of both furnishes amplestrength to hold the inseam stitches. It will also be noted that theportion 8 of the inner member is folded down against the body thereof'sothat the upstanding portion of the rib is simply the portion 5 thereof.Inasmuch as th outer member can be made of relatively-thin material, theaction of the usual beatingdown machine on the lasted shoe will be tofold the lip 5 over outwardly, thus making a relatively-fiat rib whichwill not cause any discomfort to the wearer of the shoe. 7

I claim:

1. The method of making a composite in- I beyond the edge of the foldedblank and then folding said projecting portionof said latter blank backonto the body thereof and forming the peripheral edge into alip;

2. The method of making acomposite insole comprising an inner and anouter member which consists in folding the edge por tion of a blank forthe inner member over onto the body thereof, placing said'folded blankonto the blank for the outer member with theedge of said latter blankprojecting beyond the edge of the folded blank and then folding back onitself the portion of said projecting edge immediately circumjacent theedge of'the folded blank and forming the peripheral portion of saidprojecting edge portion into a lip.

3. The method of making a composite insole comprising an inner and anouter member which consists in folding the edge portion of a blank overonto the body thereof, attaching said folded blank to another blank withthe edges of said other blank projecting beyond the edge of the foldedblank and then folding the portion of said projecting edge immediatelvcircumjacent the edge of the folded blank back on itself and intocontact with the periphery of said folded blank and forming theperipheral edge of said proj'ecting portion into a lip.

4. A composite insole comprising an inner member having the edge portionthereof folded back onto the body thereof and an outer member having theedge thereof projecting beyond the periphery of the inner member andformed by folding back on itself the portion of the outer memberdirectly circumjacent theinner member, the peripheral edge of said outermember being free and forming a lip.

In testimony whereof, I have signed my name to this specification.
